description

Technologic progres can reduce the barrier between real image and virtual image so far it is really difficult to recognize them. When virtual reality is well done, augmented reality, from virtual world to real world, is still developped. We want to project a virtual texture onto a 3D real object. By using cameras and projector, we estimate its real pose in the virtual reference by projecting a coded pattern to find points of correspondence between cameras and projector onto the textureless object, where common detector of points of correspondence are useless. We combine the calibration of the system and these points to estimate the 3D position of the object, and then register with a fine model issued from scanners. Once the registration step is done, the view synthesis can be performed and then this virtual image is projected adequally onto the real object. Such technologies can synthezise virtual and temporary textures suited to real objets without any degratation. Such textures can be easily modified, and can describe the deterioration of texture along the time ou show real objects in their original state.
